Which method is the best way to determine an ecosystems biodiversity? a. weigh all the species, and measure their total biomas. b. locate the keystone species, and identify any species that depends on it. c. count the number of species, and measure their relative abundunce. d. determine what each species eats, and identify its place in a food web.

Ans.

The ecosystem biodiversity is defined as variability among living beings (plants, animals, and microbes) present in an ecosystem.  An ecosystem biodiversity can be measured by counting the number of organisms present in that ecosystem by using several indices, such as Simpson index, which includes measurement of number of species present in an ecosystem and their relative abundance of species, known as species richness.

Thus, the correct answer is 'option C). count the number of species, and ,measure their relative abundance.'

the answer is b.) hydrogen bonds between bases.

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this
